Human studies indicate that local glucocorticoid (GC) generation within osteoblasts plays a critical role in various bone diseases. Human osteoblasts express the enzyme 11b-hydroxysteroid dehydrogenase type 1 (11b-HSD1) that converts inactive GCs (cortisone, dehydrocorticosterone) to their active counterparts (cortisol, corticosterone). This activation capacity critically depends on expression of a cofactor generating enzyme hexose-6-phosphate dehydrogenase. Enzyme expression ...
